Unfortunately, Mozilla, Netscape, Konqueror, and Opera all share a common defect. When you use the back button, cache rules are ignored, and it uses a cached copy regardless. It does matter you send no-cache headers. In my opinion the best way: 1.On page1.html there are form fields and submit. 2.Submit sends data to page2.html 3.page2.html computers date but does not send any html code but execute header('Locate: page3.html') 4.page3.html shows results If you press back button on page3.html you will return to page1.html. Your browser knows nothing about page2.html Krzysztof Dziekiewicz
